How were 240 injectors used on a turbo B16?

I see a base map for a B16 turbo with 240 injectors. I have 440’s, so I was thinking I could just change the injector size in the calibration, but now I am trying to figure out how it was possible to use the 240’s. If the fuel pressure was increased or other changes were made to get more fuel, this may not be a good starting point for my car. Is there much difference between a supercharger and turbo calibration? I have a stock motor except for a small turbo, GT25BB.

240cc injectors would not be large enough for a turbo application. 440cc injectors should be good. Start with a base calibration and then start making chages to the fuel trim tab.
